2 A mixture of ethylene and oxygen (67% C,H4 and 33% O2) exists at 25 atm and 3 o'C. Calculate: Partial fugacities of C2H4 and O2 using Lewis Randall Rule. ii) i) Activity of C,H4 and O2 iii) Activity coefficient of C2H4 and O2 The fugacities of pure components of C,H4 and O2 are 20.6 atm and 24.5 atm respectively.
